HOWTO: thread a slackline

Threaded line is one of the most old-school slackline concepts for making stronger lines. The jury, however, is still out on whether it actually makes your line much stronger (or, at minimum, the relationship between the two lines and the overall strength). The basic premise is that a tubular line is hollow, and thus we can pass something inside it, which might include another slightly smaller piece of slackline webbing. The old school setup was 1″ tubular with 9/16″ or 11/16″ threaded through it. Nowadays dedicated slackline webbings (Mantra, Aeon, etc) have somewhat obviated threaded lines; except for tricking. There are a few brand-new 32mm (1.25″) tricklines coming out that feature threading and a hybrid of polyester and nylon for the sort of “best of both worlds” when it comes to rebound/dynamicity of the line. I took some time to rethread a piece of RAGEline to point out a few of the pitfalls of threading.
